At Qualitech, a variety of welding processes are used. These include SMAW, MIG, TIG, Submerged Arc and Oxy/Acy Brazing. In addition, we also carry out Plasma Cutting. The range of components rebuilt and fabricated are made up from a wide spectrum of materials. These include, but are not limited to, Aluminium, Bronze, Copper, Cast Iron, Cast Steels, Alloy Steels, Monel, Titanium, Stainless Steels etc. To successfully weld these materials, this requires experienced coded welders who are also versatile in their techniques. We have been welding various components over the years which has enhanced our expertise in this area. Our written welding procedures for repairs have been successfully tried and tested on these materials.
Before welding any type of material, we use our Material Analyzing equipment to analyze the material composition down to its component elements. From this breakdown we can then select a welding procedure and electrode which will be able to successfully weld the metal. If required, preheat and post-heat procedures are also employed as part of the procedure. Non-destructive testing can also be carried out on critical components.
Our range of fabrication covers Silos, Tanks, Rollers, Drums, Special Storage Containers, Pump Skids, Spools and a vast range of other items. Small fabricated items can also be Sand Blasted down to SSPC-SP10 surface finish and coated with Epoxies or other painting systems specified.
