Why was WQMS Founded?

The way that inspections and crack repairs are made for heavy equipment and infrastructure in the mining industry has not appreciably changed in the last 40 years, but now equipment is pushed to do more for longer and there is a greater reliance on contractors for weld repair works. 

We have seen the consequences of this in the form of recurrent cracking issues, which snowball over time and results in increased repair costs, increased downtime, and reduced viable asset life. Much of this re-current cracking develops from poor quality weld repairs, which will typically re-crack after a short period, or even cause additional or more severe cracking than what was originally repaired. 

There are a number of reasons why there has been very little change in how repairs are managed, such as; lack of welding technical expertise by staff, difficulties in applying existing Australian Standards for welding of crack repairs, inadequate welder skills, lack of understanding about fatigue cracking. And this is just scratching the surface. It is easy to see why it all ends up in the “too hard” basket so the status quo prevails. 

We have developed a comprehensive system for weld repair management that demystifies and simplifies all aspects of welding and repair management so that mines can take control of the repair process and be confident in achieving optimised repairs that will last.  The foundations for our system are Welder Competency, Upgraded NDT data, Simplified Repair Procedures, and the System to manage the complete process. Our system is driven by people, procedures, and paper and seamlessly integrates into existing workflows and asset management. We have developed our system based on a deep understanding of the fundamentals of metallurgy, fatigue theory and welding, and built this into a simple to manage system that requires minimal welding expertise. 

We believe that the objective of a weld repair should be to restore, or even improve, the original fatigue life of the cracked component. We founded WQMS because we passionately believe that the industry should have better quality weld repairs. Our aim is to empower the mining industry so that they can expect more out of their weld repairs, and have certainty that repairs are done right.

 

The WQMS Founders

Simon Krismer

Simon Krismer

Bachelor of Materials Engineering

Chartered Professional Engineer

Certified Materials Professional

Registered Professional Engineer Queensland

Simon is renowned in the mining industry, with 20 years of metallurgy and root cause failure analysis consulting experience to the coal mining industry in the Hunter Valley and Bowen Basin coal mining regions. Having completed more than 1000 investigations, Simon knows why and how equipment fails. Many of these failures are due to welding related issues, which could have been avoided or even prevented altogether through better quality welding and attention to fatigue detail and design. He believes that understanding the mode and causes of cracking means that action can be taken to prevent cracking or improve fatigue life, rather than just “repairing” with the goal of making the “crack disappear”. Simon instigated and is leading the ACARP project “Preventing fatigue cracking via planned surface dressing of critical areas”, with the goal of developing techniques and proving the concept that fatigue life can be restored by removing the very thin surface layer of accumulated fatigue damage as a preventative maintenance action. Simon has in-depth knowledge of the fundamental metallurgical principles involved with welding, as well as the technical aspects of welding processes, and uses this to provide advice for repairs of critical components.

Simon has acted as an Expert Witness in a number of legal cases. Simon has been an active member of the Australasian Corrosion Association for more than 15 years, and is Past President of the Newcastle Branch. He has written a number of papers on failure analysis, corrosion issues and research, presented at a number of conferences, and is a guest lecturer on Engineering Materials at Newcastle University. Simon is also a PhD candidate at Newcastle University.

Eddy Constable

Eddy Constable

Cert 10 AS1796

AS2214 welding supervisor / inspector

CSWIP 3.1

Cert IV Engineering and Fabrication

Eddy is welding professional who is highly regarded by his peers and the welding industry. With over over 12 years experience as a welding professional in multiple industry sectors, although mostly in mining, Eddy has gained first-hand knowledge of the nature of the cracking and weld repair issues that the mining industry faces. This means that he understands precisely where the industry’s challenges lie and how successful outcomes can be achieved without sacrificing quality. His invaluable skills and experience, combined with his depth of technical understanding, means that Eddy brings a pragmatic and practical approach to the weld repair process.

Eddy has spent his entire welding career dedicating himself to perfecting his welding skills and professionally developing his welding knowledge along the way. Eddy’s welding discipline began with a cert III in Engineering & Fabrication (Trade boilermaker) before progressing to cert IV, he used this as the foundation towards advanced specialised welding, dragline boom welding and pressure welding proficiencies. Eddy has specialised in advanced repair techniques using some of the industry’s most technically advanced equipment available.

Eddy is a past WorldSkills Welding competitor that has represented NSW and Australia at a National level, Throughout his WorldSkills involvement he has been fortunate to receive private training from leading international expert welders. Eddy has received multiple awards throughout his career, such as the Metals trade award, WorldSkills regional gold medalist, just to name a few. Eddy continues to be a passionate Worldskills supporter where he volunteers his time as a Regional & National Judge, Mentor and is also involved in running welding training camps so that he can share his passion and knowledge with the next generation of welders. Eddy has over six years experience as a Cert 10 Welding Supervisor and Inspector, and has also travelled abroad to study at some of the industry’s key welding Institutes.
