Riselaser will exhibit at Jewellery & Gem WORLD Hong Kong 2026 from September 16 to 20 at the Hong Kong Convention and Exhibition Centre. Visit Booth 5E738 to discover our newly presented jewelry welding, laser marking, XRF precious metal testing, and laser cutting solutions. The Riselaser team invites jewelry manufacturers, repair workshops, gold buyers, retailers, distributors, and industry professionals to

Injection mold repair is often possible when damage is localized and the mold base, critical datums, and major structural parts remain sound. It becomes less attractive when a tool has structural cracking, repeated failures, obsolete components, extensive dimensional loss, or recovery costs close to replacement. This guide helps you separate mold damage from processing problems, select a repair method, and

Riselaser Technology Co., Ltd. is pleased to invite customers, partners, distributors, and industry professionals to visit us at the Beijing Essen Welding & Cutting Fair 2026. As a professional supplier of laser welding and laser cutting solutions, Riselaser will present a selection of welding automation and handheld laser welding systems at the exhibition. Visitors are welcome to meet our team,

Wondering how to resize a gold ring safely, cleanly, and profitably? Laser welding is the safest, most precise, and most efficient method for resizing gold rings today. It eliminates the need to pull heat-sensitive stones, avoids the discoloration of traditional solder seams, and allows shops to keep highly profitable repairs in-house. For independent bench jewelers, this means cleaner welds. For

Welding positions describe how a weld joint and weld axis are oriented relative to gravity. The position affects molten-pool control, penetration, deposition rate, defect risk, welding technique, and welder qualification. The designations 1G through 6G are test-position codes used in AWS and ASME qualification systems: The numbers identify test orientations—not a universal difficulty ranking. A higher number usually represents a

To program a laser welding robot, you must first define the physical weld path, calibrate the laser Tool Center Point (TCP), and set the specific laser welding recipe (power, speed, focal position). You then synchronize these movements with shielding gas timing, configure essential safety I/O, and rigorously test the program through dry runs and sample welds before initiating full production.

Laser welding is often more efficient than TIG or MIG when you need lower heat distortion, faster travel speeds, and reduced finishing work on thin to medium-thickness metals. However, TIG remains superior for maximum manual control, while MIG is typically the better choice for bridging wider gaps, heavier structural fabrication, and shops with lower equipment budgets. This guide breaks down

So, can laser welding fill gaps? Yes, modern handheld laser welding machines can fill gaps up to 1.6 mm on the shop floor. While perfect autogenous (no-filler) welding requires a strict zero-gap fit-up, adding an automated filler wire feeder allows you to bridge wider gaps efficiently. In clean-room vendor demos, laser welded joints look flawless. But out in your fabrication

A 3 in 1 laser welder is a compact, highly efficient industrial solution within modern handheld laser welding machines that combines welding, cleaning, and cutting capabilities into a single, space-saving workstation. By replacing separate machines with one streamlined system, fabrication shops are transitioning away from labor-intensive, slow traditional methods. Instead, they are adopting high-speed, direct-forming laser processing to boost throughput

Matching your laser welding wire for mold repair to the base steel’s chemistry is the only way to prevent cracking, sink marks, and polishing halos. Traditional TIG welding drops the hardness of the heat-affected zone by 10 to 15 HRC points, leaving your molds vulnerable to wear. Laser micro-welding is a massive upgrade, typically losing only 2 to 4 HRC
