What our Clients Say
Paul Bufi
QLD Parks and Wildlife
We had a persistent issue with cracking welds after cooldown due to the material composition. Matthew from MW John Welding Services quickly identified the root cause through thorough QA/QC and recommended the correct procedure. His expertise not only resolved the issue but also improved overall weld strength. Highly professional and incredibly knowledgeable — a great outcome.
