Development of the zinc coating pipe connection technology with arc soldering method using Oleh Matviienkiv, Pavlo Prysyazhnyuk, Valentyn Myndiuk Abstract The application of the arc brazing method for zinc-coated pipes joining with using the copper-based additives is suggested in this publication. This method is an alternative of the arc welding with minimal destruction of coating at the adjacent to the weld area, and it application has been analyzed and substantiated. The microstructure and microhardness research of the zinc-coated low-carbon steel pipes with the diameter of mm and wall thickness of 3. The research results have shown that joint formation takes place due to a diffusive layer at the alloy line, and the connection strength depends on its sizes. It is revealed that magnification of the intermetallic phases volume concentration in the weld metal increases its strength. It is found that the strength of the arc-welded pipe joints is affected by bevel edges. The connection with bevel edges has a greater strength with straight edges, as well as the contact area is increased with the base metal weld.

Reduction of residual stress by ultrasonic vibration during welding. Welding in Vibration Conditions — Critical Approach. An advantage of the protective coatings is enhanced corrosion resistance, particularly important in car cavities, on flanges of bottom parts of doors and overlap joints [9, 10] Fig.

The application of protective coatings also contributes to the reduction of costs by simplifying or even eliminating some stages of production e. An example of the production process simplification is presented in Fig. Scheme of seal reduction using sheets with CPP coating [11]; a conventional, b with the use of CPP The weldability of protective coatings with an organic layer is ensured by adding pigment in the form of powdered zinc or Fe2P [9].

By exerting pressure during welding, conductive particles create paths for flowing current. Organic coatings, however, also significantly contribute to the increased wear of electrode tips. The manufacturers of steels with such coatings recommend that during welding, a material with a one-sided organic coating should be located from the faying interface side so that it is not touched by electrodes [12]. During the welding of galvanised sheets, the interface between a material being welded and an electrode tip is better than during the welding of sheets without protective coatings.


For this reason it is necessary to apply higher welding current. The welding of protectivecoated sheets provided with an organic layer requires lower current values due to the higher resistance of the interface between an electrode and the material being welded due to the coating material.

The welding of sheets with protective coatings contaminates an electrode tip with substances contained in the protective coating.

This fact has particular implications for batch welding, performed on robotised stations, where as many as 60 welds per minute are built up [13].
