Welding questions:
Yes, since any form of welding that utilizes an electric arc is in the classification of ‘arc’ welding.
Clarification: Arc welding is the general classification of many sub-classes of welding. Among them are processes commonly known as MIG, TIG, Inner shield or gasless, Dual-shield, stick, submerged-arc, and many more.
Yes.
Clarification: ‘Heli-arc’ is a manufacturers name for their equipment that performs the TIG (properly classified GTAW) process. We use TIG to weld aluminum, stainless, brass, regular carbon steel, and more.
Yes. “Certification” is a legal term of the completed process of qualifying welders. We can qualify you to most AWS codes and explain the whole process in more detail at that time.
Yes. In MIG (GMAW), TIG (GTAW), Flux-core (FCAW), and Stick (SMAW); all position structural welding. Also, some Pipe. We are also Certified Welding Inspectors and NDE technicians in MT, UT, and VT to meet all your welding and inspections needs.
Clarification: There are many different welding codes for all the different welding processes pertaining to many different applications (pipe, structural, bridge, pressure vessels, equipment, etc.). Some of them overlap and some of them do not. Being certified as a structural stick welder does not qualify you to do stick welding on pipe.
NDE is Non-Destructive Evaluation/Testing (NDT). It is performed by various processes such as MT (magnetic particle), UT (Ultra-sonic), PT (Dye Penetrant), RT (Radiographic or X-ray), etc. Even VT (visual) is an NDE procedure as it does not destroy the weldment being examined.
