What Are Metal Burrs in Laser Welding? Metal burrs are raised edges or attached fragments left after cutting, punching, drilling, milling, or stamping. In a laser welding cell, they are usually an upstream part-preparation problem rather than a defect created by the welding beam. Welding can produce spatter, excess weld metal, undercut, or an uneven […]
What Are Welded Assemblies? Welded assemblies are finished structures made by joining two or more fabricated metal parts with permanent welds. The starting components may be laser-cut sheet, bent panels, machined plates, tubes, brackets, or standard structural sections. Once fitted and welded, they function as one unit—such as a machine frame, cabinet, battery enclosure, equipment […]
MIG welding aluminum can deliver fast travel speeds and high deposition rates, but only when the wire path, shielding gas, surface preparation, and heat input work together. Aluminum wire is soft, the oxide layer melts at a much higher temperature than the base metal, and the metal conducts heat quickly. Those three facts explain most […]
Laser cutting is changing agricultural equipment manufacturing by moving many sheet and tube parts from fixed tooling and manual layout to a digital cutting workflow. A manufacturer can cut brackets, guards, frame plates, tube joints, holes, slots, and prototype parts directly from CAD files. The practical gain is not a vague promise of “more precision.” It […]
A good weld is not simply smooth or attractive. It must have the required size, fusion, penetration, profile, and freedom from unacceptable defects for the drawing, welding procedure, and inspection standard. A bad weld shows visible or hidden discontinuities that exceed those acceptance limits. Visual inspection is the first filter, but it cannot prove internal soundness. […]
A handheld laser welder can shorten cycle time, reduce heat input, and make repeatable sheet-metal joints easier to produce. Those gains depend on joint fit-up, material, operator training, shielding gas, and a controlled laser-safe workspace. The strongest business case comes from testing representative parts, not from accepting a universal “four times faster” claim. For production […]
Fiber laser can cut galvanized steel efficiently. The catch is the zinc coating. It reacts to heat before the steel substrate reaches cutting temperature, so the process can produce extra vapor, spatter, dross and coating damage if the pierce, gas flow and extraction are poorly controlled. Treat galvanized sheet as a coated material with its […]
Choosing laser power from a maximum-thickness chart is one of the fastest ways to buy the wrong machine. Maximum thickness is usually a boundary test. Production capacity is what the machine can cut repeatedly, across your real nesting mix, while holding the edge and tolerance your customer accepts. The right laser cutting power matches four […]
Aluminium laser cutting is routine on a properly configured fibre laser, but it is less forgiving than cutting mild steel. The metal conducts heat away quickly, its surface can reflect part of the incident energy, and its low-viscosity melt must be cleared before it freezes under the sheet. That combination exposes weak process control fast. […]
A laser chiller is a closed-loop temperature-control unit that removes heat from a laser source, cutting or welding head, and other water-cooled components. It circulates coolant through the laser system, absorbs unwanted heat, transfers that heat to a refrigeration circuit, and returns the coolant at a controlled temperature. Stable cooling protects more than the laser […]
Fiber laser cutting is one of the fastest ways to turn mild-steel sheet into production parts, but laser power alone does not determine the result. Good parts come from matching the steel grade, thickness, assist gas, nozzle, focus, piercing method and downstream finish. For most factories, oxygen is the practical starting gas for medium and […]
Nitrogen, oxygen, and compressed air can all remove molten metal from a laser-cut kerf, but they do not produce the same edge or the same production economics. Use nitrogen when a bright, low-oxide edge matters, especially on stainless steel and aluminum. Use oxygen when cutting mild steel benefits from the heat released by oxidation and […]
Laser cutting stainless steel makes sense when a factory needs repeatable profiles, fast changeovers, clean geometry, and less manual work between the drawing and the finished part. A fiber laser can move from one programmed shape to another without a dedicated hard tool, so it suits both mixed batches and stable production. That does not […]
Panel bender vs press brake compared — how each bends, a spec-by-spec table, and how to choose by thickness, volume, and operator skill.
NC vs CNC press brake explained — open-loop vs closed-loop control, precision, speed, maintenance cost, and a 4-metric buyer’s guide, with real shop-floor data from machines we actually run.
This guide provides a professional framework for importing industrial laser machinery from China. The core principle for every buyer: Total Landed Cost typically exceeds the machine’s base price by 20–25%. From the workshop: Most first-time buyers fixate on the cutting chart and forget the edge quality their customers actually pay for. In our experience the […]
This guide moves beyond brochure marketing, providing a detailed breakdown of real-world costs based on the Profit and Loss (P&L) statements of 200+ Senfeng customers across 30 countries. From the workshop office: Buyers compare sticker prices and miss the number that matters — cost per part. A higher-power or better-specified machine that cuts faster and […]
