VLBS-Welding Block ASK-VLBS-16

The welding block is forged out of the material 1.0577+N (St 52-3) and is marked with the identification number of the permissible nominal WLL.

The patented distance lugs have a distance measurement function for the required spacing to the root weld (approximately 3 mm).

Welding should be carried out by a qualified person according to EN 287-1.

The joint faces must be free from impurities like oil, colour, etc.

The chosen welding point must be suitable for the corresponding force introduction.

The engaging surface must be plain.
Given an uneven surface, the weld blocks have to be re-adjusted.

Root welding: beginning of the root weld + fillet weld in the middle of the welding block.

Carefully clean the root before placing the covering weld seam.

Separate welding instructions for the welding procedure and filler metals are supplied with the VLBS.
