It is one way to "Stress Relieve" the weld joint. As the weld metal metal cools it contracts and hammering on the weld expands it. On thick sections it is done after every layer of weld. Often used when welding cast iron or other metals with a low COE (Coefficient of Expansion).
What else can I help you with?
How do you cut pipe ends for welding perpendicular joints?
DOWN AND DIRTY: For an end or corner joint, cut each intercepting piece at a 45. For T joints, cut the top of the post with two opposing 22.5s to give you a full 45 and cut your top rail with a corresponding 45 to the longitudinal centerline. Peen pieces into place if necessary. Saddle markers are available at most oilfield supply or welding supply stores. They are available for all common pipe sizes... Simply clamp it on the pipe and mark your cut. No peening necessary.
What are applications of explosion welding over conventional welding?
The biggest application of explosion welding is the cladding of flat plate.
What is horizontal welding position?
Look at a wall. Imagine welding on that wall from left to right or right to left. That is horizontal welding.
How many welding and joining processes are available commercially?
There are numerous commercially available welding and joining processes, with the most common ones including arc welding, MIG (metal inert gas) welding, TIG (tungsten inert gas) welding, resistance welding, and laser welding. Additionally, processes like spot welding, electron beam welding, and friction welding are also widely used in various industries. The choice of process often depends on factors such as the materials being joined, the desired strength of the joint, and production efficiency. Overall, the diversity of welding and joining methods enables tailored solutions for specific applications across different sectors.
Who is responsible for standardizing the welding symbol?
Any standards that are welding related in the United States are designated by the American Welding Society (AWS).
What is peening?
Shot peening is a process in which a media is accelerated and shot at a product in order to pound and bend the product into the desired shape and finish. Peening removes little metal from the finished product, and is used to give a pronounced finish.

What Welding electrode can be used to weld A 36steel to AISI 4140 steel?
I have experience when my team welded "JIG Ladle" A36 to AISI 4140, we used electrode E7018 with SMAW process. The important thing for this welding's prehating during welding min. 180 degree celcius and did peening the weld beads to minimize residual stresses. After welding covered by blanket for slow cooling. Regards, Asep S (asep93st@yahoo.com)
Does shot peening causes High Hardness HRC Value?
Shot peening does not inherently cause high hardness (HRC) values; instead, it is a mechanical process that induces compressive residual stresses in the surface layer of materials, which can enhance fatigue resistance and overall strength. While shot peening can improve the performance of materials, any increase in hardness is typically related to the material's properties and treatment processes, rather than the peening itself. Therefore, while shot peening can contribute to improved mechanical performance, it does not directly increase the HRC value of the material.
What are Techniques for peening a weld?
PeeningPeening is a procedure that involves lightly ham-mering a weld as it cools. This process aids in relievingbuilt-up stresses and preventing surface cracking in thejoint area; however, peening should be done with carebecause excess hammering can work harden and in-crease stresses in the weld. This condition leads to weldembrittlement and early failure. Some welds are cov-ered by specific codes that prohibit peening so youshould check the weld specification before peening.

Difference between ERW and SAW welding?
SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.
