Hierdurch     wird die mangelhafte   Stelle an diesem Punkte erhitzt und das Schweissmetall b angebracht, wenn es bis auf die Schweisstemperatur erhitzt worden ist, wobei es durch den elektrischen Strom von der positiven nach der negativen Elektrode, d. h. an die   mangelhafte   Stelle fortgerissen oder weggesogen wird.

   so dass das angebrachte Metall genau

  Process and electrode for electrical welding.
 EMI1.1
 



   With the previously known methods for welding by electrical means, difficulties arose, especially when welding seams on the lower side of the objects.
 EMI1.2
 is. z. B. under ship steam boilers and the like.



   The present invention relates to a simple and practical method for electrical welding and a suitable electrode for this purpose, whereby the welding of seams on the lower side of the objects can be easily accomplished.

   The welding is done in the following way. After the coating has been removed from the end of the electrode e, this is brought closer to the seam a, with the current

 has been made. As a result, the defective point is heated at this point and the welding metal b is attached when it has been heated up to the welding temperature, whereby it is caused by the electric current from the positive to the negative electrode, i.e. H. is torn or sucked away to the defective point.

   so that the attached metal is accurate

 Binding agents, such as a potassium salt, are made up of substances which, by forming compounds or alloys with the weld metal, act on the weld metal and give it the appropriate degree of hardness.
