Depending on their hydrogen and alloy content, some metals require preheating before they can be welded. Preheating is a preventative measure that protects materials from cracking, distorting, spalling, and thermal shock.
Why It's Important to Preheat Before Welding:
Without preheating, the weld affected zone is hard and cold. Welding causes this surface temperature to change dramatically. Rapid heating and cooling increases hydrogen levels and stresses the material considerably - leading to cracks and weakened points. Preheating prepares and treats the surface prior to welding.
Customized Solutions for Preheating:
Not sure whether or not your material should be preheated? Depending on the alloy, carbon content, size, and rigidity of your part, preheating may to your advantage. Choosing the right preheating temperatures and method will depend on the type of metal in question. Robotworx' technicians will help you determine how much (if any) preheating you need. Ask us about the possibility of building a customized system that will handle the preheating and welding in one unit.

The Heritage Elementary School RoboVikes, one of the robot clubs RobotWorx sponsors, visited this week to learn about industrial robots.
These local 4th and 5th graders were able to see examples of workcells, gantry robots, parts positioners, and EOAT. Arc welding, polishing, and cutting applications were discussed as well as the benefits of automation.
RoboKids is a brand new 4-H program for 3rd through 5th graders. The students study robotics by working with Lego kits to build and program robotic vehicles and other machines. The 4-H robotics program was started in the Marion, Ohio area.
RobotWorx is very supportive of robotics education. The company offers sponsorship support to robotics clubs and competitions on a case-by-case basis. For more information, contact RobotWorx at 740-383-8383.
In robotic welding, the angle of the welding torch often determines the quality and appearance of your weld. The best welding angle for each application can vary, depending on the type of material and thickness of the workpiece. The three primary torch angles are pull, push, and straight.
Push Angles - Since push angles are easily programmed, they are preferred by most robotic programmers. A push angle is created when a robotic welding torch moves forward, welding in front of itself.
Advantages of using push angles:
-
The robot is able to create smooth,more desirable weld
-
A cleaner surface due to better gas shielding
-
The robot creates a more desirable bead appearance
Disadvantages of using push angles:
-
Increase of visible spatter
-
Weakening of material due to a slow cooling rate
Pull Angles - Another option is the lag angle, more commonly known as a pull angle. Pull angles are designed to work opposite of push angles, creating the weld behind the torch as it moves.
Advantages of using pull angles:
-
Spatter is better controlled
-
Narrow bead width is achieved
-
Deeper penetration
Disadvantages of using pull angles:
-
The bead appearance has larger raised areas than usual, which can lead it to overlap.
Straight Angle- A straight angle is created when the robotic welding torch is programmed to weld from a perpendicular position. Straight angles can cause many problems because they apply direct force to the material. Sometimes this focused welding approach can burn or blow through the material being welded.
