Technical specifications
This alloy has a small coefficient of thermal expansion of 1.5x10 -6 1 / ° C (at a temperature of -80 ° C + 100 ° C), which determines its use in the manufacture of parts of instrumentation that operate with minor changes in climatic temperatures, in these temperature limits a constant size.

Invar welding
The most widely used is argon-arc welding by a tungsten electrode with a current of direct polarity. This method, thanks to its great versatility and the provision of high quality joints, replaces manual arc welding with coated electrodes, gas welding and even submerged arc welding. The non-consumable electrode is usually connected to the negative pole of the generator, the product to the positive pole. When welding with reverse polarity, the arc is less stable. Much less often, argon-arc electric welding is used with a consumable electrode.
Storage
Finished products are stored in closed warehouses or under a canopy, where adequate protection against mechanical and other damages is provided.
