Welding at Sea

Hi Cruisers, being the owner of a 34ft Steel Sloop, I would like info regarding 'Do-it-yourself' welding repairs at sea.. what type welder is required to run from generator and what equipment do I need. The boat is constructed of corten steel. Could stainless steel be welded with this equipment (in emergency) and also any other advice is welcomed....cheers Harry 'FUTURE DAYS'

Re: Welding at Sea

You need a generater that pumps out 7 KVA for a start,

You can buy a small MIG welder that can do all your repairs, Use stainless wire in it, and you need a small bottle of argon gas,

Or you can buy a CADDY welder if you know how to weld with electrodes. no gas needed

Welders do suck a lot of power,,

Re: Welding at Sea

Harry,
A stick welder(SMAW) will cost you less and, if you go for a generator or alternator system, will pack away easier. Here's a link to some Zena systems:
Portable / Mobile DC Welding Equipment Designed for Use in Remote Locations

Yes, you can weld mild steel, Corten & other HSLA steels and 300 series stainless with these rigs, or any DC welder.

Unless he's improved his cheap alternative, variable current control was not a feature of Brent's system.

Thanks for the quick response Bangaboat!!....will check it all out...I need to start from my generator, see if it has required out-put....Cheers Harry

Re: Welding at Sea

There's a company in Arizona that sells these plasma cutter, TIG combos for around $750. Add a small bottle of Argon gas and you can do mild steel, stainless and if you have a HF unit added, you could do aluminum as well. You'd have to pack three different types of welding wire but the argon could be used for all metals.
You can run this off of 220 VAC or 110 VAC and it automatically adjustes to the coltage it sees.
Very portable and the plasma will cut easily 1/4" stainless plate.

Re: Welding at Sea

First off, do a Welding course at Tafe,
That will teach you the basics of welding,
Your necks on the line, welding is not just pick up the welder and go for it,
You do need to know what your doing, a basic course might be 6 months, Minimum, I just dont know,

Dont be like the idiot in the welding add, use long sleeved shirt and cover your body where ever the rays can hit exposed skin, and do not look at the pretty light with your eyes, it will burn your eyeballs out, near instantly. and the pain is horrendous for days.

CIG have a portable stick welder, commonly called a Caddy, Weldskill 170 amp, its a new release, excellent power output, for around $400-00, will run a Low hydrogen 4mm stick with ease, about 0ne foot long X 5 inches wide X about 8 inches high, Will weld whatever you need on a boat, it should run on your boats generator, very light and comes with a shoulder strap. and the welding cables as a package, Any welding supply place close to you will show you it,
A small packet of CIG Weldcraft, Weldall electrodes, .25 or .35 thick, they will weld all materials that you might need to weld, keep them very dry, about $80-00 per packet.

I bought the one with the full TIG attachement, but thats a tad over $800-00, same size welder, but does a lot more things. you dont need that one,
I use this one for on/site work. I am an on/site Boilermaker/DLI Welder full time,

If you want to cut a patch out, use a 5 inch grinder with 1.5 thick cut off wheel, cheaper than Oxy or a Plasma,
All dollars are in Aussie dollars,

Re: Welding at Sea

You might consider doing an oxy-acetylene course and getting a small set-up for that. Good for cutting and welding; gives a cleaner weld than stick or wire-feed; and a whole lot safer when standing knee-deep in water.

Too slow, he'd warp the heck out of the plate & he wouldn't get the penetration.

It may be slow, but he did say it was for repairs, not production. Not any more likely to warp the plate than with any other method. I have no idea what you mean about penetration; as with any welding method, preparation and technique will take care of that.

O-A may have its disadvantages, but he won't need to generate a whack of energy, worry about being electrocuted, or invest in an electrode oven.

The heat from an oxy set will warp the plate, Its too bloody slow, he knows nothing about welding, let alone oxy welding, He has 6 hours between tides unless he hauls it out, Twenty minutes with a welder, the jobs done, including cutting the offending bit out,
The school will teach him about welding and water,
As for penetration, you know nothing about welding either,
Weldall electrodes dont need preheating or an oven.
