The weld area needs to be free of oils, paints, heavy rust, and in most cases mill scale. Ideally you want to grind the joint area back about 1 ½ of an inch to clean metal. All joints must be braced to avoid distortion from weld shrinkage. When it comes to welding heavy plate you will need to brace your joints more than thinner metals. The shrinkage from multi pass welds will distort the joint to the point where it is no longer square.See more on gowelding.orgIs welding carbon steel easy?Welding carbon steel is easy and does not have any real obstacles. It welds fine in all positions and produces a quality weld. The only possible issue could be from welding in the vertical up position. This position typically requires a groove because the weld is always very convex. Another issue to watch out for is cold lap.See all results for this question
