In seam welding
, the electrodes used are in the form of rollers as shown in Fig.
This article highlights the special challenges of applying pulsed Nd:YAG lasers in precision joining of guidewires and similar structures, motion and laser control techniques beneficial to hermetic laser seam welding
of implantable devices, and new metals joining production methods made possible by the availability of "green light" (532 nm) pulsed Nd:YAG welding lasers.
This is achieved by the reduced build up of dirt particles due to the tubular construction the sloping surfaces and the seam welding
. Which along with the open construction design, including the reduced number of support legs (with added stability), facilitates cleaning.
Their latest innovation is to use plasma welding rather than mash seam welding
on lines manufacturing high-end, water-conserving washers featuring was tubs made of stainless steel rather than cold-rolled steel.
Plus, its sheet construction facilitates sterile seam welding
while its resilient formulation and durable clear wear-layer work to simplify maintenance and extend the lifespan of the floor--making Lonwood with Foam softer underfoot and more economical than wood and many other surfaces on a lifecycle cost-basis.
Hermann's technology is suitable for a wide variety of applications including: spot and seam welding
, bonding multiple layers of different materials, laminating multilayer products, engraving or embossing labels, slitting of decorative elements, die cutting and perforating in both lengths and cross direction at high speeds.
So the switch from silicon to seam welding
was a logical one.
"The present technique for the welding of steel cans is known as mash seam welding
, which can weld at 100 metres per minute", said Mr Trevor Johnson, of the centre.
But the seam welding
was carried out by heat fusion with oxygen-acetylene.
The origin of this is known to be due to the formation of a void in the material, commonly known as a "keyhole." Both in cutting and drilling operations, but certainly also in spot welding and seam welding
, the keyhole provides the means for deep penetration of the laser energy despite its surface absorption.
From the development of the first sewing machine with thread trimmer and the invention of continuous ultrasonic welding technology to the latest in programmable CNC stitching machines and automatic pocket setters, PFAFF Industrial has a well-recognized track record of sewing and seam welding
innovation around the globe.
