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.

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)
What is the difference between butt weld and socket weld?
A butt weld is a weld made between two straight cut profiles , a socket , or plug weld is made between a surface and a hole.
Which one is stronger field weld or shop weld?
When done correctly it doesn't matter where a weld is made.
How do you calculate weld deposit metal weight?
At first, the area of cross section of the weld, length of the weld, volume of the weld in cubic inches, weight of weld in cubic inches. To express in formula: Weight of Weld Metal = _ Êx ÊBase Êx ÊHeight Êx ÊLength Êx ÊWeight of Material.
