Come On Christmas Posted January 18, 2012 Posted January 18, 2012 I bought an antique roll crimper oft eBay. The guy shipped it in a cheap box and the wind up handle broke in two. Can I have it welded as it is cast? Thanks, Shameless
J. Mark Flint #31954 LIFE Posted January 18, 2012 Posted January 18, 2012 It is likely cast iron as opposed to cast steel and the bottom line is that yes it can be welded, but it is a bit tricky and results are unlikely to be guaranteed. Use nickel rod, I would preheat the part to 500 degrees and after welding I would return the part to a 500 degree oven and slowly cool it by reducing the temperature over a period of a couple hours. There are other methods for welding cast iron, but none are foolproof. It might be cheaper to just buy another roll crimper. I have one lying around for 12 ga if you are interested.
Dusty Hill, sass # 49256 Posted January 18, 2012 Posted January 18, 2012 Many shops will tell you that you cannot weld cast. The best way to do it is to have it tig welded. But you will need to find an exsperienced well seasoned welder to do that. they are usually retired guys who a have shop set up in at their home. Sometimes you may get lucky and find a younger guy, but they are few. As JMF said replacing it may very well be the better way to go. If the weld is not done right cast iron will crack again right along side the weld.
Blackwater 53393 Posted January 18, 2012 Posted January 18, 2012 JMF is right! Find a shop that does engine block and head repair. They will usually have a line on a good welding facility if they don't do it themselves.
Assassin Posted January 19, 2012 Posted January 19, 2012 Yep, JMF is correct. Heat he part, inconel rod, then slow cool. I used to weld up cast iron "grape vine" decorative stuff. It was fragile and would shatter if dropped. However your part can be repaired if done properly. LL'
The Original Lumpy Gritz Posted January 19, 2012 Posted January 19, 2012 I have done this many a time. Preheat the area with a gas or LPG torch. Then with a "stick" type welder use a #6013 "mud-rod" you can do it. LG
Rancho Roy Posted January 19, 2012 Posted January 19, 2012 I've brazed this type of thing many time. Never had one come apart if done properly. Pre-Heat is very important whether welding or brazing.
Guest Chief Posted January 19, 2012 Posted January 19, 2012 Roy B has the easiest and most cost effective way,brazing will hold for ever.

Pre-Heat is very important whether welding or brazing. Yup, me too... I've had brass hold cast when nickel welding rod wouldn't... Warm the whole piece and be careful not to let it cool too quickly after you're finished...
