Weld decay is a form of intergranular corrosion that occurs in stainless steel welds when they are exposed to certain environments, particularly those with high temperatures. This corrosion can lead to degradation of the weld's mechanical properties and overall performance. To prevent weld decay, proper welding techniques and selection of appropriate filler materials are crucial.

What is sugaring in a weld?
Sugaring in a weld refers to the formation of a crystalline structure on the surface of the weld in stainless steel due to overheating during the welding process. This sugaring can make the weld more susceptible to corrosion and reduce its overall strength. It is important to avoid sugaring by using proper welding techniques and protecting the weld from excessive heat.
What is weld spatter?
Weld spatter refers to the small bits of molten metal that can be expelled from the welding process. It can occur when excess welding wire or flux is present, leading to weld spatter landing on the workpiece or surrounding areas. Weld spatter can cause damage to the welding equipment, affect the quality of the weld, and create safety hazards.
What is the function of slag for welding?
Slag in welding acts as a protective layer on the molten weld pool. It helps to prevent contamination from the atmosphere, improve the weld's appearance, and facilitate the solidification process of the weld metal.
What does heavily oxidized weld deposit mean?
A heavily oxidized weld deposit refers to a weld that has been exposed to oxygen during the welding process, leading to an excessive formation of oxides on the surface. This can weaken the weld's integrity and compromise its mechanical properties. It is important to avoid excessive oxidation during welding by using shielding gases or fluxes to protect the weld from oxygen.
Why the slag come in welding?
Slag in welding is formed when the flux coating on the welding electrode melts and lays over the weld pool. It helps protect the weld from atmospheric contamination, acts as a coolant, and facilitates the removal of impurities from the weld. After the weld cools, the slag can be easily removed.

How close can one weld be to another weld?
Depends on what you are welding, but generaly welds can meet, or even weld on top of a weld.
