How do you calculate interpass temperature in welding?
Interpass temperature is the maximum temperature a weldment should be allowed to reach between weld passes. If a pass is completed and the temperature is in excess of the interpass, it should be allowed to cool before continuing.
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.

How is the root opening size determined in welding?
the root opening is the distance between joint members at the root of the weld before welding. the root opening must be accurate so that excess welding is not necessary.
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.
How is photokeratitis caused?
by excess exposure to UV light. This can occur with sunlight, suntanning lamps, or a welding arc. It is called snowblindness because the sunlight is reflected off of the snow.
How do you control distortion in welding?
To control distortion in welding, it's important to use proper clamping and fixturing to hold the workpieces in place during the process. Preheating the materials can help reduce thermal gradients, while selecting appropriate welding sequences and techniques, such as stringer beads or weaving patterns, can minimize heat input. Additionally, allowing for controlled cooling and using filler materials with low shrinkage properties can further mitigate distortion. Regularly monitoring and adjusting parameters throughout the welding process is also crucial for maintaining dimensional accuracy.
