Special Features of Our CNC Welding
Perfect for Thick Metals
Our systems can weld steel plates up to 50mm thick with deep penetration. This is perfect for heavy equipment and building supports.
Works With Thin Materials Too
We also do laser welding for thin materials (less than 1mm) without warping or burning them. Great for electronics housings and medical parts.
Custom Tube Welding
Need welded tubes for frames or pipes? We use CNC tube bending and then weld them perfectly. This makes strong frames for cars, bikes, and furniture.
Aerospace-Grade Welding
Our NADCAP standard welding meets all rules for airplane parts. We can weld titanium, special aluminum, and other space-age metals.
Medical-Grade Cleanliness
For medical devices, we use special clean rooms and processes that keep parts sterile. Learn more about our medical CNC machining services.
Key Materials for CNC Welding
Common Metals You Can Weld
Stainless Steel
Aluminum
Titanium
Copper Alloys
Stainless Steel
Stainless steel is a top pick for CNC welding. It does not rust. It stays strong in salt water.
- It has high strength – 550 MPa
- Great for marine parts
- Used in food tanks
- Lasts a long time in wet places
Stainless steel welds keep 95% of their strength after welding.
Aluminum
Aluminum is light but strong. It works well in planes and cars.
- It weighs much less than steel
- Has good heat flow
- Comes in many types (6061, 7075)
- Needs special AC welding
Aluminum welded joints have 310 MPa strength. This makes them good for parts that must be both light and strong.
Titanium
Titanium is very strong for its weight. It works well in:
- Medical tools and parts
- Aerospace parts
- Marine uses
Titanium costs more – about $25 per kg. But it is 50% lighter than steel. This saves fuel in planes and cars.
Copper Alloys
Copper moves heat and electricity well. It can be hard to weld but works for:
- Electrical parts
- Heat pipes
- HVAC systems
Copper parts move heat 50% faster than steel parts.
