What will be the effect of moisture in welding?

Moisture in welding can lead to several detrimental effects, including hydrogen embrittlement, which can weaken the weld joint and cause it to crack. It can also result in porosity, where gas pockets form within the weld, compromising its integrity. Additionally, moisture contamination can hinder the proper fusion of materials, leading to poor weld quality and reduced mechanical properties. Proper pre-weld preparation and handling of materials are essential to minimize moisture-related issues.
