Welding joints, techniques and expertise are applied to countless industries, from automotive and aeronautical, to manufacturing and shipping. Welders are required to have versatile knowledge about the different types of welds and how to perform them, even when the welding required is not as comfortab...
This study aims to investigate the effects of different types of welding current on the characteristics of Nickel Aluminum Bronze Alloy (NAB) such as microstructure, hardness, depth/width ratio and dilution by using Gas Metal Arc Welding (GMAW). The mechanized GMAW was employed for the bead on...
The difference between flat welding flange and butt welding flange: 1. Different forms of welds: The welds of flat welding cannot be radiographically inspected, but the welds of butt welding can be; flat welding is two fillet welds and butt welding is one butt girth weld. 2. The nominal p...
Technological and Economical Aspects of Arc Welding of AL 5754 Heat in these welding types are supplied by electricity, so the first major component is the power supply. A guide to welding basics--from the tools to their uses There are some 50 different types of welding operations have been ...
Welder qualification testing consists of questions on the types of welding symbols, safety, welding processes and positions, types of welds, material handling, and more. The hands-on qualification test is conducted by a certified welding inspector who will provide a visual inspection and observe the...

2、 Longitudinal deformation of welded joints 在焊接过程中,焊缝及其附近产生的塑性变形区的主要原因是纵向变形,对接接头塑性变形区的存在,必然导致焊件纵向弯曲变形或纵向缩短。 In the welding process, the main reason for the plastic deformation zone in the weld and its vicinity is the longitudinal deformat...
and preserves the complete metal flow line, the mechanical properties of the forgings are generally superior to those of the same material. Important parts with high load and harsh working conditions in related machinery, in addition to simple rolled plates, profiles or welding parts, are mostly ...
Different types of steel beams can also be assembled by welding separate structural steel plates together. In this way, each flange is attached to the web separately. Welding can decrease the weight of the beam, and add strength. This is how plate girders are made. They are welded, bolted ...
