How must cracks be repaired?

Explanation:
Cracks are defects that seriously weaken a weld and can grow with use. The only reliable repair is to remove the cracked portion and reweld with sound material. Welding over a crack hides the defect and can trap it, while other fixes like epoxy filling don’t restore the metal’s strength or metallurgical integrity and won’t meet welding codes. By removing the bad section and producing a new weld, you ensure proper fusion, eliminate the crack, and restore the joint’s strength and safety.
