I will dinjin. As you said -lots of farmers and quarry/mine fitters have welded stuff like this. I used to be a rep for Strata - Repair and Maintenance Alloys, and have demonstrated their product to many a fitter and engineer, with great results. I'll keep you posted how it all goes,thanks.

I have priced up making a new gear and it was more than a second hand gear box and the cheapest of them I could find was NZ$2000 + gst(with NO warranty).A new gear alone from Hino $1462+tax.Welding it is not a problem-or profiling it-but the HAZ as you guys mentioned is.Maybe I should look into...

Following a tragedy inside my Hino truck gearbox,and a fruitless hunt for parts, I have decided I have no option but to build up-weld the chipped/missing teeth. I was planning to tig weld(after a pre heat) with a filler rod for dissimilar steel that work hardens and is machinable. As welded...

Hi Clambone, Go ahead with your instincts about the Linoln.It's generator friendly and a little beauty to work with!As for your concern about the laptop and other gubbins,my advice would be not to weld beside any of them and use surge protectors where you can. Cheers TW Weld.

Hi-your best bet would be to locate the manufacturers/suppliers of the panels/cladding and obtain their recommendations.They usually supply full fixing recommendations and point out other important factors to consider before the product is applied to the building. Hope this helps in anyway. TW Weld.

Hi there ps3081. I have a Castolin booklet in my hand(British Version) and this is what is said about the 690 electrode:- High strength metal arc electrode for the joining and o verlaying special steel parts. Provides a combination of both strength and ductility for the welding of components...

Hi there test, Cant put my finger on any suppliers as such,but I would suggest contacting a company who desing and manufacture moulds for "Plastic injection moulding". A simple design could be sitting in somebody's filing cabinet or hard drive. Best of luck-TWWeld.

Hi jminn-Agree with Mike on the rod;- note also that you can use an argon/helium mix shielding gas-generates a hotter arc and if you have adjustable wave shapes you can opt for better cleaning and less penetration or vice versa. www.lincolnelectric.com have some great tips on their site. Hope u...
