1. Technical essentials of argon tungsten arc welding
1.1 Selection of tungsten argon arc welding machine and power polarity
TIG can be divided into DC and AC pulses. DC pulse TIG is mainly used f...
Welding defects can be divided into two main categories based on their location in the weld: internal defects and external defects.
External defects are located on the outer surface of the weld an...
The thermal conductivity of copper and copper alloys is more than 5 times that of carbon steel. Welding is prone to pores, lack of fusion, and thermal cracks. The selection of welding wire direc...
Introduction
Aluminum welding requires the right filler material to ensure strong, crack-free joints and excellent corrosion resistance. Among the most widely used aluminum welding rods are E4043...
Among welding methods, Tungsten Inert Gas Welding (TIG) and Shielded Metal Arc Welding (SMAW)—commonly referred to as “Arc Welding”—are the two most prevalent processes. Those unfamil...
The submerged arc welding process is the most ideal choice in the important application fields of pipelines, pressure vessels and tanks, track manufacturing and major construction. It has the simpl...
