Where is slot welding used in construction


Quote by clevertherm
Hello!

It's a very simple box.
At the front and back, the floor is bent up over the KWL.
The side walls are either vertical or inclined slightly outwards.
The benches serve as floats and make the box unsinkable.
Entry and exit are via the bow. From the inside over firmly welded steps (= cavities = buoyancy bodies) and from the outside either directly on a bridge or something.

@Inselwart:
Please read through my topic. There the construction is described down to the smallest detail.

It won't work without your cooperation. But that's not rocket science either.

You should find out about the required permits beforehand. I don't see any problem for purely private use. As soon as it goes into the commercial (also free) area, the requirements are completely different.
But I'm not an expert on that anyway.

best regards

Hello Clevertherm
Yes - actually - I also consider the boat to be a very simple box -
just a work boat. I can also do all the work myself (at least I was able to do that two years ago - in the meantime I had a bitter pancreatitis, with all the trimmings, such as the intensive care unit, etc., which almost took my life) - but now I don't have enough Time and no inert gas welding device in the appropriate size or quality, which should be - right?

The side walls, I think, even have to be inclined at least at the height of the submerged and empty swimming waterline, or 10 cm above and below it at at least 20 ° ... I'll tell you something about it:
Last winter I was there to pick up two of my employees, craftsmen, with the newest, actually completely, in many ways most stupid steel boat of our boat ranks from the land and drove very slowly and carefully through our fairway, which was kept fairly clear in the ice. The ice all around was about 15 cm thick and the channel was half full with already rounded chunks of ice / clods, when the big icebreaker (man, what's his name now?) Fur seal ?? came around the corner and turned across to us in the Tegelersee (our channel was about 100m away from the ice-broken fairway of the Oberhavel in the "quasi pack ice"). For such a small 2mm-walled steel tub, 15cm of ice is a lot - nothing for the icebreaker.
So he pushed our fairway in / away / flat in no time ... but we were still there !! and despite the most violent declining, it came closer and closer.
The boat with an almost invisible side part inclination (i.e. almost vertical sides) crunched and shook violently when there was a huge crash and the boat lifted 20 cm with a jerk and a 2 meter wide clod to the right of us broke off the let the boat come down again - whoosh.
So the boat was definitely not pushed out but almost squashed.
I have to go through the ice in winter - at least until it has reached a certain thickness, which then means that I / we can safely walk over the ice 100 meters in the direction of Tegelersee from the gully. Afterwards, when "our ice" becomes crumbly at the end of winter, the ice on the Havel is actually already thawed or at least partially gone by ship traffic and wind and currents and then in the meantime I have the boats overland / island by wheel loader to the Havel side the island.
Furthermore, I imagine that boats that have a slightly sloping side wall at the level of the waterline also have better ones
Cornering properties.
When it comes to floats, I have a different opinion than most of the other discussants. I mean that I can use the space much better: e.g. for life jackets, several paddles / oar blades,
plenty of lines, fenders, etc.
If the worst comes to the worst, the so-called floats are used to prevent the boat from drowning - well, what about the passengers? .. namely nothing .. they have to stick to life jackets or lifebuoys anyway (literally !!). The boat - well, how deep can it sink - I don't know of any place around me that is deeper than, say, 5 meters. From the depths you can still salvage a boat with even 1 tonne weight very well (I've already experienced it), but let's not talk about drowning / capsizing / accidents, we'd rather make sure that the boat is not at risk. The only form of buoyancy body that I can well imagine is a double bottom, which in turn harbors dangers that are invisible and, if so, even greater danger, namely that rusting from the inside.
I had also imagined firmly welded steps made of frames with galvanized grids (but on each side with a railing in the middle - because of our walkways). A fold-down ramp at the front would be awesome, but also a luxury.
My cooperation is necessary - I think so too, but I can also dispose of employees' working hours - we will see what will be necessary. The most important thing is first of all a welder who has a feeling for how he can fry such a body together without it bursting apart again on its own because of the heat tensions.

So: who has this person's address?
If they are unemployed, they might even officially join
be employed on the island!?

And you can't rent such a welding machine?
