Corner connection of profile pipes without welding

Hello dear readers and DIY !
Steel shaped pipes are a very common construction material, and have a wide range of applications. The connection of structural elements is most often done by welding.
However, not every one of you has a welding machine, but you need to assemble very simple structures, for example, for furniture .
In this article Denis, the author of the YouTube channel “DENDEN TV”, will tell you how you can make reliable corner joints of shaped pipes without welding.

This method is quite simple, and a minimum of tools are required to implement it.
Materials required for homemade products.
– Steel profile pipes 20 × 20 mm, wooden beams
– Wood screws with countersunk heads
– Furniture corner brackets.
Tools used by the author
– Screwdriver
– Countersink, drills for metal
– Self-centering drills
– Miter saw, vice
– Bulgarian
– Cutting and flap discs – Circular saw
– Vernier caliper, semi-automatic core, marker.
Manufacturing process .
So, for the demonstration, the master will use a square profile pipe with a cross section of 20 × 20 mm.
First of all, he cuts four pieces of the same length using a miter saw. This machine is convenient in that it gives even cuts at the desired angle. Of course, you can use a grinder instead, or a hacksaw for metal.

Bars with a section of 17 × 17 mm are cut from this material so that they fit tightly into the pipe.

Corner connection of profile pipes without welding Now you can connect structural elements by screwing long self-tapping screws recessed heads into place.

Corner connection of profile pipes without welding This structure can be additionally strengthened with furniture angle brackets.
For this, the master applies brackets to the inner corners, marks future holes with a marker, and kernite centers.

Self-centering drills are designed to simplify the task of drilling holes for such corners or loops. They do not require preliminary marking, and the accuracy will be higher.
