Core Selection Logic: Power Defines Capability, Application Defines the Choice

Before selecting the power level of a handheld laser welder, two key questions must be clearly defined: What materials do you usually weld, and what is the maximum material thickness? Laser power directly determines weld penetration depth, welding speed, and material compatibility.

STRION LASER’s product lineup is engineered around these practical requirements. Each power level is precisely positioned to serve specific applications and production scenarios.

Below is an overview of the core welding capabilities of STRION LASER handheld laser welders at different power levels (based on official product testing and compared with conventional welding processes):

It is clear that as laser power increases, the achievable welding thickness for various materials rises significantly. However, higher power does not automatically mean a better choice. Matching the power level to real production requirements is the key to avoiding overinvestment or insufficient capacity.

Power Model Breakdown: Clear Choices Through Real Scenarios
