スポット溶接とシーム溶接

極小スポットから連続シームまで

 

レーザー溶接には0.1mmに満たない極小スポット溶接から数mm厚さのシートメタルの連続シーム溶接まで様々な方法があります。高速で溶接すると溶接した部分は幾何学模様になります。溶接には出力およそ40Wから数kWのレーザーがよく使われます。溶接スピードはレーザーの出力・材料の組み合わせ・表面形状・そしてレーザーのタイプにより決まります。例えば波長が異なれば吸収率も異なります。

 

Spot welding of copper conductors for electric motors

For this application a high number of welds per part have to be realized. With scanner and fiber laser, the laser beam can be positioned from weld to weld within milliseconds. Adjusted scanner movements melt the copper so that broad welding gaps can be bridged. Due to their high absorption into highly reflective materials such as copper, the fiber laser is the right tool for this application. Another advantage of laser welding with the fiber laser is the low heat input due to very short process times. Therefore damaging the isolations because of high temperatures can be avoided.

 

For this application we recommend: FL Series

Laser Welding of Air Conditioning Cooling Pipes

For welding the aluminum of this air conditioning part, ROFIN fiber lasers are the ideal choice. The shorter 1um wavelength is much better absorbed by high reflective materials such as copper, aluminum or brass, compared to longer wavelengths.

For this application we recommend: FL Series


 

Laser Welding of Brake Sensors

The steel of ABS brake sensors is welded with high-power fiber lasers. Besides the brake sensors also various other sensors like pressure sensors, force sensors and air-bag sensors are welded by laser.

 

For this application we recommend: FL Series


 

Laser Welding of SCR Injectors

No matter if finest spot welds or welds with several kilowatts power - the possibilities and the advantages of the laser beam are manifold.

 

For this application we recommend: FL Series

 

熱交換機用管

To produce this component in one process step, a stainless steel strip is coiled up spirally onto an untreated stainless steel pipe and simultaneously welded with the laser. An important aspect of this process is the good accessibility of the weld seam to the laser beam. Besides, the complete weld connection between the rib and the pipe precludes crevice corrosion.

 

For this application we recommend: DC Series, FL Series
