Post-heating in welding is used to relieve residual stresses and reduce the risk of cracking in the weldment. It helps in achieving a more uniform temperature distribution throughout the material, promoting better ductility and toughness. Additionally, post-heating can improve the mechanical properties of the weld and surrounding base material, enhancing overall performance.
heating then controlled cooling of a weld to reduce stress
You can try, but it will not stay. The heating and cooling of the manifold will cause the JB weld to fall off.You can try, but it will not stay. The heating and cooling of the manifold will cause the JB weld to fall off.
post heating : after completion of weld is not cool below to preheat or room temp. further it is heat by applying addition heating system to certain period of time and temperature to evalute hydrogen from weld metal.
The seal weld in a structure is used a weld used for tightness. Specifically this type of weld is used for holding in liquids or gaseous materials.
circumfrencial weld is sometimes referred to as Girth weld. its just another term.
TKY weld joints are tubular joints used for welding. They are expressly used for when fabrication of a structure is necessary.
A buttweld is a junction welded by heating two ends of metal with a weld plate and joining them under a specific pressure.

6010 is a high cellulose sodium based electrode, which can be used to weld carbon steel pipes.
A closure weld is a technique of sealing an object in which powerful electrical current or heat is used to melt the surfaces together. This is used extensively in industrial applications.
seam welding is a process that produces a weld at the faying surfaces of two similar metals where its used depends on which metal you look to weld
