Jusqu'ici, les cordons de soudure qui doivent être durs,

8 à 9 % de chrome. S'il s'agit de former des cordons de soudure

  
moins tenaces, on emploie, pour la soudure, des baguettes de

teneurs en chrome allant jusque 4,50 %. Or, on est parvenu

Les soudures c, d et e se caractérisent par une dureté élevée pour une grande ténacité après le refroidissement à l'air. Elles supportent des efforts de percussion sans se déformer ou se fissurer. Leur résistance aux projectiles pénétrants est très grande. Par une trempe des soudures dans l'huile, elles prennent les propriétés d'un acier à outils, qui peut être soumis à des

On peut rapporter les fils comme arêtes sur les tranchants et les outils de percussion.

  
Le fer servant de matière fondamentale des fils peut avoir une teneur en silicium de 0,3 à 1,5 % et une teneur en manganèse de 0,3 - 0,8 %.

  
Les fils de la composition suivante se sont revoies parti-

So far, the weld seams which must be hard,

  
tough and wear-resistant were executed with threads

8 to 9% chromium. If it is to form weld seams

  
less stubborn, we use rods of

for increasing the alloy content.

  
The following examples of welding wires having carbon and chromium contents within the limits in accordance with

 <EMI ID = 9.1>


  
Welds c, d and e are characterized by high hardness for high toughness after air cooling. They withstand percussion forces without deforming or cracking. Their resistance to penetrating projectiles is very high. By quenching the welds in oil, they take on the properties of a tool steel, which can be subjected to

  
 <EMI ID = 10.1>

  
The wires can be used as edges on cutting edges and percussion tools.

  
The iron used as the basic material of the wires can have a silicon content of 0.3 to 1.5% and a manganese content of 0.3 - 0.8%.

  
The sons of the following composition met again

  
 <EMI ID = 11.1>

  
The latter wire is particularly resistant to percussion forces with simultaneous wear by friction by rock powder.
