This article describes a weld seam tracking sensor which |
|
has a type of pulse modulated infrared beam as its signal |
|
light source. Going through signal reception filters and |
|
'adaptive elimination of noise' processing, it is |
|
possible to effectively overcome interference from |
|
electric arc light. Making use of the light source pulse |
|
driven characteristics, the instantaneous signal power is |
|
greatly added to, improving the adaptation of optical |
|
sensors to the surfaces of pieces of work. The sensors' |
|
structure is simple. Their volume is small. Their |
|
sensitivity is high. And, they are capable of realizing, |
|
at the same time, automatic tracking of weld seams in the |
|
two horizontal and altitude directions. It is capable of |
|
precision tracking in both submerged arc and open arc |
|
automatic welding. |
