In laser cutting, how can piercing and blowholes be addressed?

Piercing and blowholes are very common issues in laser cutting, representing key challenges that affect cut quality, processing efficiency, and operational safety. First, let’s clarify two concepts: Piercing: Refers to the process of using a laser to create an initial hole in the material before ... Read More

Principle of Laser-Oxyfuel Hybrid Cutting Machine

Laser flame composite cutting usually refers to “laser oxygen cutting”, which is one of the main laser cutting processes (the other two are laser melting cutting and laser vaporization cutting). It does not mean “laser-generated flame,” but rather a hybrid process that uses a laser as... Read More

After a laser cutting machine malfunctions, how do you locate the focal point?

After a laser cutting machine malfunctions, returning to the zero point (the machine coordinate system origin) is a critical step in restoring normal operation. Please be sure to follow the principle of safety first and operate with caution. The following are the detailed steps and handling metho... Read More

Reasons for slag hanging at the bottom when oxygen c utting carbon steel

When cutting carbon steel with oxygen, slag hangs down at the bottom (the lower edge of the cutting surface). This is a very common phenomenon, professionally known as “slag hanging” or “slag adhesion”. The main constituents of this slag are high-melting-point oxides and i... Read More

A Laser Maintenance Reminder Triggered by Cooling Water Quality Issues

Recently, a customer’s 6,000-watt fiber laser suddenly developed a water leakage fault, forcing it to shut down. Following an emergency disassembly by the technical team, it was discovered that the interior of the fiber rod was heavily encrusted with white scale and verdigris. This confirmed that... Read More

Cut 20mm carbon steel, the whole cutting seam is inclined to the right

6000 watt fiber laser, cutting 20mm carbon steel, the overall kerf is tilted to the right, and oxygen is used as an auxiliary gas. The following are the troubleshooting and solutions for the current situation. Combined with the specific situation, especially the power of 6000 watts, the core of t... Read More

Laser cutting bright surface skills

Using fiber laser cutting machine to cut bright surface materials (such as mirror stainless steel, high-gloss aluminum, copper, brass, etc.) has fundamental differences and great advantages with the use of traditional CO₂ laser, but it also requires special skills to obtain the best results and e...

How to solve the problem of thick plate perforation with residue affecting cutting

When laser cutting thick plates, the residue (slag) generated by perforation affects the cutting quality is a common but optimizable problem. These residues are usually caused by improper energy control during the perforation process, mismatch of gas parameters or unreasonable process parameters.... Read More

How to solve the burr generated by laser cutting metal

The burr generated when laser cutting sheet metal is a common process problem, which usually indicates that the cutting process is not optimal. To solve this problem systematically, it is necessary to check and adjust from multiple dimensions such as equipment, materials, process parameters and a... Read More

How to solve the sticking slag when laser cutting aluminum plate

Laser cutting aluminum slag (also known as hanging slag, slag) is a common problem, mainly by the high thermal conductivity of aluminum, low melting point, easy oxidation and molten state viscosity and other characteristics. In order to solve the problem systematically, it is necessary to optimiz... Read More

Laser cutting machine nozzle loss of several common cases

In fiber laser cutting, the nozzle is an extremely critical and vulnerable consumable. Its loss directly affects the cutting quality, gas consumption and production costs. Common nozzle loss mainly has the following several situations: Physical impact and wear (This is the most common and direct ... Read More

What happens when sparks are splashed to one side during laser cutting?

It is not normal for sparks to be deflected to one side during laser cutting, which usually indicates that the cutting process is asymmetric or unstable. This can affect the quality of the cut and, in severe cases, may damage the nozzle or lens. The following are the possible causes of the proble... Read More
