    shielding gases

    Hi, It is a combination of the weld pool temperature and the cover gas conditions. Hard to tell you which one is responsible in your case without seeing the process. May be you want to play with the parameters and check whether there is any improvement. Good luck

    shielding gases

    Hello, The cross jet, being perpendicular to the beam direction will keep the spatter away from the focussing optics but will not provide protection to the weld pool against oxidation from atmospheric air. Normally compressed air is used for cross-jet and an inert gas, also called cover gas...

    shielding gases

    Hi, Sure. Blowing some nitrogen at very low pressure thro an orifice of quarter inch opening will surely help to limit the plasma, improve the weld depth and appearance both. I suppose the cross jet that you mention is compressed air flowing across the lower surface of the lens and...

    shielding gases

    Hi, What is the desired weld depth? Helium is generally best for plasma suppression but it is expensive. One of the main sources of the spatter is the beginning of the weld. Do you ramp in and out the power? Ramping helps to reduce the spatter and get a smooth beginning of the weld. Is the...

    shielding gases

    Hi, The gas selection depends upon a number of factors like laser power, beam quality, material, weld depth requirement etc. Please provide some more info. Regards

    Machine code to cut 1/4in stainless on Hankwang Koba 3015

    Hello, To offer you some help, some information is necessary on the make and power of the laser. Also do you have the possibility to cut with high pressure nitrogen or not? Regards, VinayakLaser

    Laser Cutting Platinum

    Hi! Sorry for not comunicating before. From various exchanges, it seems that you have discared all other mechanical alternatives and are already using lasers to cut Platinum. If that be the case, it seems that you are interested in getting a regular industrial system which will cut things for...
