The AMWU has employed welding inspectors to attend building sites around the state. They will be checking if contractors have NATA certified welding procedures. They will also be checking to see that all welding personnel are currently qualified. This is not a reference to whether a contractor has a Cert 2 or Cert 3 in Engineering but more that welders are currently qualified to AS/NZS 1554.1 by means of a macro test and current NATA report. Welding personnel can also be qualified to AS2980 or by possessing an AS1796 welding certificate.
Global Welding Technology is able to assist companies and contractors to achieve compliance with AS/NZS 1554.1 in a cost effective and timely manner.
Please contact us to assist you.

Australian Standards have released a new version of the Gas and Liquid Petroleum Pipeline Welding Code. There are a great deal of changes from the 2007 version. All weld procedures are now required to be signed off by an IIW International Welding Engineer. Requirements for Repair welding Procedures have also changed. Welding Supervision and Inspection requirements have been upgraded. Welder qualifications are valid for 12 months. NDT requirements have also been amended.
Global Welding Technology is able to assist with all aspects of the new code to enable you to achieve compliance.

Welding Inspection.

Why have it? Inspection of welding, it’s an extra cost to my business. It’s just more paperwork. I have ISO 9001 so why do I need to do more?

Let us help you tap into the work and methodology of a welding inspector.
Firstly let us say that the work of a welding inspector is viewed by most people as very similar to the work of a policeman. Let’s not get too close but if I need you please come to my aid. In some respects this may be true depending on the actual role of the welding inspector
Welding inspectors are usually employed by 4 groups; the fabricator, the intermediate client, the end client or by some authority figure such as the court or Worksafe. How the inspector operates depends on who they are actually working for. If its Worksafe they will operate very much like a policeman as a critical situation has arisen that needs to be addressed legally. If they work for the end client or intermediate client it will be on a basis of obtaining the best interest for the client but this may or may not hurt the fabricator. The ideal situation is for the welding inspector to be employed by the fabricator. This ensures the inspector is always operating with the focus on the fabricator manufacturing lean, efficiently, in compliance with the specifications and drawings, with the focus on maximizing profit and improving the fabricators reputation in the market place.
The role of the welding inspector involves monitoring the job from material delivery right thru to packing and delivery of the finished product. This will include ITP’s and welding procedure specifications.
To accomplish this the inspector will involve technicians from other disciplines such as radiography, ultrasound, crack testing, coating testing and the like to fulfill obligations of the contract or specifications. He/she will liaise with engineers and the client and any of their representatives. The inspector will make sure that the inspection levels are in compliance with the contract. Sometimes it is assumed that 100% inspection is required but this is rarely the case. It is usually in the range of 0% to 50%. Yes 0% meaning that some types of inspection are not required.
The level of inspection is determined by the construction code and the category selected within that code. More and more in Australia it is required that international codes will be used. The welding inspector is fully trained in codes from all over the globe. It is the experience of the welding inspector that enables them to guide the fabricator to operate efficiently but within code requirements thereby saving the fabricator money. Losses that occur in a business and regarded as “normal to doing business” can be reduced if not eliminated by the welding inspector. As the inspector becomes more and more part of the organization the employer and employees trust in him/her grows. This trust allows changes to be made to systems and work practices that reduce errors, reduce rework and scrap. This often amounts to a lot more cost savings that far outweigh the outlay for the welding inspection services. Another area very much overlooked is getting the weld inspector in at the time of quotation where he can often give advice on pitfalls, errors in the specifications or drawings and better methods of manufacture and outsourcing some elements of the contract.
Global Welding Technology are able to offer guidance on all of your weld inspection queries from visual inspection through to Non Destructive Testing (NDT) and Coating Inspections with NACE inspectors.

Welding Supervision
 
Why do I need a Welding Supervisor? I already have a foreman or I run the factory myself. This is just another cost to running my business. This blog will help bring to light the difference a Welding Supervisor can make to your bottom line in a positive way.
  
Firstly let’s look at exactly what a Welding Supervisor is or more precisely what a W.T.I.A. AS2214 or AS1796 Welding Supervisor is.
 
The AS2214 Structural Steel Welding Supervisor has completed a WTIA run course for Structural Steel Welding Supervisor and has passed the exams for it. He is now fully trained in welding theory, Australian Standards, non destructive testing (NDT), inspection requirements, quality assurance, weld procedures, on the job monitoring of welding variables and welding supervision of staff either in a factory or on site. The codes he is trained to work with are the AS/NZS 1554 series and AWS D1.1. It is also required that to begin the AS2214 course that the candidate be a tradesman thus assuring a certain level of experience at the work front.
 
The AS1796 Pressure Vessel Supervisor, also known as a Cert 10 Supervisor, has also completed a WTIA run course for Pressure Vessel Supervisor and has passed the exams for it. This is a much more in depth training course than the AS2214. Pressure vessels and associated piping can be lethal and at the least destructive if they fail in service. Hence the responsibility is much greater for a Certificate 10 Welding Supervisor.  The Certificate 10 supervisor is now fully trained in welding theory, metallurgy, Australian Standards, International Standards, non destructive testing (NDT), inspection requirements, quality assurance, ITP’s, weld procedures, on the job monitoring of welding variables and welding supervision of staff either in a factory or on site. The codes he is trained to work with are the AS/NZS 1210, 1228, 3992, 4037, ASME 9, ASME 31.3, AWS codes, ISO codes and API standards. It is a pre-requisite that a Cert 10 candidate possesses a WTIA Welding Certificate and has several years of experience in place. This assures adequate experience for his role as a WTIA Welding Supervisor.
 
Generally the above training descriptions are not met by the foreman or by the owner(s) of the business. This leaves the business open to errors at quotation level, errors at purchase level, errors at fabrication level, errors in the welding, errors in the coatings and errors in the testing of the finished goods i.e. NDT. This is where the value of a WTIA Welding Supervisor is found. With the avoidance of errors all these negative impact costs to the business can be avoided or at the very least minimized. You are able to manufacture your goods at best speed with minimal waste or error so that your clients only see a high quality item manufactured in full compliance with the construction code with all required testing completed. This ensures repeat business for your company. Using the experience and high training of the WTIA Welding Supervisor you will also be able to take on more complex work that will yield higher profit margins.
 
The use of an external WTIA Supervisor is also very cost effective as you only pay for the hours the Welding Supervisor is in attendance. The use of an external Welding Supervisor also adds to the credibility and integrity of your company as he will not be under the influence of management to yield under pressure from tight schedules. It maintains the “at arm’s length” perception of integrity of the work you are performing. Most welding codes also state that any Supervisor involved with the manufacture cannot be involved in final inspections and most end clients stipulate the same in their specifications.
 
Global Welding Technology is available 24/7 to assist you with your welding supervision, welding inspection, NDT and NACE inspection needs.

Hi, are you a steel fabricator or site welding business? If so, are you aware of your obligations to the end client, the job contract, the drawings and specifications? This is a greatly misunderstood area and we would love to help you manage it.
 
Firstly all structural engineers specify the Australian Standard AS/NZS 1554.1 or AS/NZS 1554.5 on their standards and on their drawings. What does this mean for you the fabricator or the site welder? Well these standards are created to make sure all parties have a foundation, a level playing field, to work on as an absolute minimum guarantee of a certain level of quality. It lays out the requirements for design, as in weld size, length and placement, for the minimum training level required, do you need a full tradesman or not, for the testing required, x-ray or crack testing, and for the documentation that you are required to produce to satisfy the job requirements.
 
Let’s cover these items one at a time.
 
Design requirements
Is the construction AS/NZS 1554.1 or .5? Generally most work is specified as AS/NZS 1554.1 SP. Occasionally, in high stress or fatigue situations AS/NZS 1554.5 will be specified. This is usually carnival equipment or structures like the Southern Star Observation Wheel in Melbourne. The rating SP compared with GP concerns weld quality and how it is inspected. It addresses weld defects such as cracks, undersize, undercut and porosity for example. SP rating is much more stringent. SP category requires more NDT, non destructive testing, such as X-ray or ultrasound than does GP. SP category requires a higher level of testing on weld procedures and welder qualifications.
Training requirements
AS/NZS 1554.1 requires the use of certified tradesmen. This is NOT an indentured tradesman with Cert 2 or 3. It is a tradesmen that has been tested to the weld procedures being used in the last 6 months via a welding supervisor witnessed test approved by a NATA laboratory. Most work in the structural trade is fillet welding. Some of it is performed in the vertical position. The welding operator must be tested for the type and position of weld to be used. A simple mock up fillet weld in 10mm plate, witness and tested will allow a welder to weld on the job for the next 6 months. This applies to the welding performed in the factory and on site.
Testing and inspection requirements
Under AS/NZS 1554.1 all welding must be subjected to some inspection. This applies to work fabricated in the factory and on site. The selection of GP or SP category by the engineer is what drives the level of inspection. Using a W.T.I.A. accredited Welding Supervisor will make all this very streamlined for your firm. He will determine what level of testing is needed and what percentage must be assessed with that method. Generally everything is visually scanned for gross defects and missing welds then a closer visual inspection is carried out on a percentage of the work. NDT such as x-ray or magnetic particle testing will follow to pick up small defects the eye cannot see. Inspection of welding is your best defense against mistakes and defects. Records of all testing must be kept on file and presented to the client at the end of the job.
Documentation required
All welding and fabrication work must be performed using qualified procedures. The simplest level of procedures is the SWMS system. This applies to each task being performed such as drilling, cutting or welding. More critical to the job and to quality is the formulation of a qualified welding procedure specification, a WPS. This is a document setting out all the settings to be used by the welding operator. This ensures no matter who does the welding it is done correctly. Welder qualification records, WQR’s, prove the staff have been tested to weld adequately to the provided WPS. NDT records prove that all of the job has been tested with the correct test and to the appropriate percentage level. Any repairs that arise must also be documented and records kept.
 
With the assistance of a W.T.I.A. Welding Supervisor all of these tasks will be performed seamlessly and will result in your firm actually saving money owing to lower rework levels. All of this quality system can be sued as a fantastically powerful sales tool to your potential clients as many other firms are non-compliant.
