Although MIG welding is one of the three most common types of welding, it's not the oldest. That distinction belongs to arc welding, better known as stick welding. Somewhat harder to learn than MIG, stick welding equipment is generally cheaper, including the "stick" electrode welding rods. A...
#3) Induction Welding In addition to arc and laser welding, there’s the fusion welding process known as induction welding. Induction welding is distinguished from all other types of fusion welding because it’s the only one in which there’s no direct contact between an object’s surface and...

Generally, welding deformation can be divided into two types: overall deformation and local deformation. In practical structures, these two deformations exist at the same time. Overall deformation is the change of the size or shape of the whole structure, which usually occurs in the form of longi...
In the following infographic you can take a look at these 5 welding joints to find out how they look: These are the top 5 five basic types of welding joints that every newcomer to the trade should know, but professional welders need to be familiar with more advanced, specific a complex ...
Passing the test on a 3/8″ thick plate, with backing in the vertical position, you would then be qualified to weld in the flat, horizontal and, vertical positions. Welding Certification Processes The most four common types of welding processes used for certifying welders are: SMAW / ...

Twenty-three types of test coupons were prepared and welded with varying welding parameters to create the different weld bead profiles. The intention and the methods used for each test number are shown in Table 1. Table 1. Summary of each test number. 2.2. Measurement of Weld Bead Profiles...
arrangement was optimized using a central composite design (CCD), the response surface method (RSM), and the genetic algorithm (GA). The results showed that when the initial welding spot was located close to the contour of the patched blank, the bending moment was greater when the weld spot...
