Welding grate

[Gestrike]

Unsure if this is the right forum section, but here goes:

I have come across a lot of rebar and I'm eager to weld grids for the garage windows. However, I've never done any welding before, so I have quite a few questions.

What type of welder should I be looking at? Is MMA the way to go? Will a cheap one, like from Lidl, work, or are they completely useless?

Can you "loosen" already existing welds (it's an old welded pergola I've acquired)?

Releasing welds is done with an angle grinder. An MMA welder will surely work, but a MAG is easier. Regardless, it is a relatively simple welding task. So it's a good starting project if you want to begin welding.

Okay, thanks for the tip. Do you think this one from Biltema is sufficient?

One more thing, maybe a dumb question... If you're welding at home, do you need some form of adaptation of the space you are in? Or can you just be in the garage however you want?

There will be welding sparks during welding, and when cutting/grinding with the angle grinder, glowing metal shavings will spray out, so keep fire hazards in mind. If it's a concrete floor and plastered walls, it's probably fine, but remember that there shouldn't be any flammable materials nearby that could ignite. (The angle grinder can spray quite far.)

As for fumes from welding, they're not very healthy, so good ventilation/exhaust is preferable, but standing by an open garage door isn't a major problem.

Not any way at all, but for small jobs and with a bit of thought, at least you won't burn the house down

Why not go to the building supply store and exchange the rebar for reinforcement mesh instead?

Or can you stay in the garage just like that?

The driveway might work?

Why not go to the hardware store and exchange the rebar for reinforcing mesh instead?

Then you don't need to weld and don't get to buy a welder And you won't learn it either

MMA is great because it allows for welding outdoors in all weather conditions. Mig/mag is quite sensitive to wind.

No, exactly Half the point of this project is that I want to learn the craft itself.

There will be welding splatters during welding and when cutting/grinding with the angle grinder, glowing metal chips will spray out, so be mindful of the fire hazard. If it's a concrete floor and plastered walls, it's probably fine, but remember that there shouldn't be any flammable material nearby that could ignite. (The angle grinder can spray quite far).

Regarding the welding fumes, they are not very healthy, so good ventilation/extraction is preferred, but standing by an open garage door is no big problem.

Not just anything goes, but for small jobs and with a bit of thought, you won't burn down the house

I've got the angle grinder under control, have worked a lot with it over the years.

The welder you linked to is a MIG that requires either shielding gas or flux-cored wire. Gas cylinders are expensive. Flux-cored wire is both expensive and gives (in my opinion) a poorer result. I would rather buy one of these: https://www.biltema.se/verktyg/svetsning/svetsar/svetsinverter-mma-140dc-2000035249 Then you use regular welding electrodes (sticks), but you get a welder that you can use outdoors even if it's windy, which is tricky if you have MIG with shielding gas. You can also weld stainless steel with it using special electrodes.

I have a handle on the angle grinder, I have worked a lot with it over the years.

That's good, you don't want the broom with glowing sparks to spray against the pant leg, made of synthetic material, and melt it so it sticks to the burn wound that can form when it gets a hole...

Just as an example, but don't ask how I know...

Oki, thanks for the tip. Do you think this one from Biltema is sufficient?

Don't know anything about that welder, but it requires a 16amp fuse, for a couple of thousand more you can get a better esab welder
