Consulting - ASME Code - Precision Welding
FAB Source welding services include custom fabrications and repairs of existing items. Our skilled MIG and TIG welders are ASME Section IX and AWS certified, and are also trained to read engineered plans and make high-quality parts to spec. Our welding equipment is precisely calibrated semi-annually for quality assurance.
Our experienced craftsmen excel in making quality welds with gas metal arc welding (MIG), gas tungsten arc welding (TIG), and shielded metal arc welding (stick electrode). We select the most appropriate welding process for the job at hand by considering several factors, such as:
Type of material being welded,
Thickness of the material,
Type of welding power source and the amount of current available, and
Gas Metal Arc Welding (Metal Inert Gas - MIG) consists of feeding a bare metal filler wire--made of the same material being welded--in conjunction with a shielding gas through a hand held torch unit. The welding wire picks up electric current supplied by a standard power source. On contact, it creates an arc that does the welding. For routine joining applications, a MIG welder probably offers more advantages than any other welding process.
Gas Tungsten Welding (Tungsten Inert Gas - TIG) uses a non-consumable tungsten electrode and shielding gas that protects the welding area from contamination. TIG welding can be done in all positions, including overhead. Its concentrated heat and precise control of the arc allows thin material (0.01 inch) to be welded. Although TIG welding is a relatively slow process, compared with wire-fed MIG or flux cored, it provides high quality welds. However, it also requires greater operator skill level than the other processes.
Shielded Metal Arc Welding (Stick) uses a consumable, flux-coated electrode containing mild steel, stainless steel, cast iron or various other alloys. These electrodes are selected to match the base material being welded. Other than the power source, electrode holder and work clamp, no other equipment is required. Stick welding is more forgiving than MIG when welding on dirty or rusty metal, but not recommended for overhead welding or with thin materials.
