it's a mixture between what is called " beed welds"
Various techniques used during the repair of aircraft and fabrication.
Various types of steel is in modern damascus such as O1,1084, etc forge welded together.
It is called aluminum welding. Aluminum can be TIG welded, the most common method, or oxy-fuel welded, or stick welded, or MIG welded.
modern ships are welded, older ships use rivets to hold the steel together
Body In White: the main structure of a vehicle, usually made of steel pressings welded together to make a strong and stiff frame.
What have you welded ?
It is called aluminum welding. Aluminum can be TIG welded, the most common method, or oxy-fuel welded, or stick welded, or MIG welded.
Welded joints can weaken a structure by creating stress concentrations at the weld area, which can lead to cracking or failure under loading. The heat-affected zone around the weld can also experience changes in material properties, such as reduced toughness or strength, further contributing to weakening of the structure. Insufficient or improper welding techniques can introduce defects like porosity or lack of fusion that compromise the integrity of the joint and overall structure.
Pipes that have been welded (or melted) together.
Double submerged arc welded pipes has two types, one is spiral welded pipes, and the other is longitudinal welded pipes which are different from EFW pipes.
The heat input during welding can affect the grain structure of the welded material. Higher heat input can lead to larger grains, which may reduce the mechanical properties of the material, such as strength and toughness. Conversely, lower heat input can result in finer grains, which generally improves the material's mechanical properties. Parameter control is important to achieve the desired grain structure for optimal performance of the welded joint.
