What is the best way to fix cracked cast iron without welding? Rutt’s machine shop uses metal stitching, a time-proven technique for fixing cracked or broken cast iron metal components through topical metal splinting.

It is a cold process using cast iron block crack repair inserts and pins. It is especially effective when used to repair brittle cast metal objects with little risk of altering the metal as might occur from the heat of welding.

Cast Iron Crack Repair Steps

Patterns of holes are drilled in the object across the line of fracture

The holes are then shaped to fit the joining insert

The joining insert is placed in the new anchor holes

Additional holes are drilled in line with the fracture

The new holes are filled with metal anchors, creating a pressure-tight joint

The anchors and inserts are usually ground flush, resulting in a permanent, low-profile repair

Metal stitching is a reliable, cost-effective alternative to welding. It also faithfully retains the original shape of the repaired object since no heat is used (which can alter the composition of the metal or reshape the surfaces of the object). Metal stitching also reduces stresses on the repaired surface, allowing the new splint to adjust to future thermal pressure while permanently shoring up high stress points on the repaired object.
