Lead is a metal that is widely used in various types of industries, primarily in the chemical and nuclear industries, due to its unique performance properties. Minimal interaction with the most active substances allows it to be used to create containers intended for their transportation, without fear of leaks.
Preparing for lead welding
To carry out lead welding, it is necessary to carefully prepare the material for this procedure. To do this:
- it is required to clean the edges of the metal to a shine, at least 3 cm from each edge of the edge;
- after stripping, etching with acetic acid is additionally used (this procedure can also be replaced by rinsing with a solution of chlorine carbon), which will ensure maximum surface cleanliness
The cleaning procedure must be carried out directly before welding , as the metal gets dirty very quickly. As a last resort, you can re-treat the edges of the welded metal to be sure that no dirt particles get into the weld, which significantly reduces its quality.
How lead is welded
Lead welding can be carried out in a wide variety of seam positions:
- the fluidity of this type of metal allows horizontal welding;
- ease of melting makes vertical welding possible.
Welding types applicable to lead
For the processing of lead, it is most important to use gas welding equipment, since the most common technology for welding this material is gas. It is used for welding lead surfaces with a thickness of 0.8 - 30 mm. For thicker materials, this technology is also considered appropriate. Most often, gas welding technology is used for welding pipelines with small diameters, surfacing lead on other metals, etc.
Also, if it is planned to use arc, pulse or cold welding technology, it is possible to use electric welding equipment. The expediency of using a specific technique depends on such an indicator as the thickness of the metal. For example, arc welding as well as cold welding can be used for thicknesses not exceeding 4 mm.
Another lead welding technology is an explosion.
