The HAZ (heat affected zone) travels down and to the sides of the weld. The slower your travel speed and/or the higher the amperage setting means the more heat input which means the wider and deeper the HAZ will be.

Whether HAZ is higher in gas welding or arc welding?
Larger in Gas Welding. In all arc processes the HAZ is concentrated in a couple inches around your bead. In gas welding it can be double or triple that size.
What are welding defects?
1. crack 2. spatter 3.distortion 4. haz 5 blow holes
What is preheating in welding?
welding cast iron is not reccomended although it can be done,myself i have always had the best luck by preheating the cast iron to almost cherry red then using a low hydrogen electrode such as 7018 which is fairly common,there is also an electrode known as inconel which contains the alloy nickel,but its hard to find and very expensive
When welding in a vertical position the arc length is longer then welding in a flat position?
Actually I usually crowd the puddle when welding vertical up. The longer the arc length the more the arc can wander.
Which is hotter oxy and acetylene welding or MIG welding?
This is something of a trick question... Every metal has its own melting point that must be reached to weld the material. The difference between Oxy-ace and Mig is the Heat Effected Zone. This is the blue and purple area around your weld in which the Microstructure and properties of your base material change. Oxy-Ace will have a much wider HAZ.
What is Arc length in welding?
Arc length is the distance from the tip of the electrode to the workpiece.
How do you ask for something?
"I CAN HAZ" or "CAN I HAZ?"
What is lap length for welding in reinforced bar?
The lap length for welding a reinforced bar will depend on the size of the bar that is being welded. If the bars are different diameters when lapped, the lap length should be calculated using the lesser diameter.
What is haz?
A word generally replacing and tense of have (have, had, has). It can as well be used before any verb or auxiliary verb. It may also be spelled as "has." I haz a blanket. I haz a Halo collector's helmet, but my roommate stole it. He haz a blanket. I haz can do it! I haz jumped over the blanket.
Can I haz the Cheezburger?
Noz, noz can haz cheezburger.
What is the correct arc length for arc welding?
3/8 inch
What welding defect is considered the most severe?
1. Surface Cracks 2. Under bead / HAZ crack 3. Root Crack 4. Inclusion 5. Concave profile 6. Weld undersize.
