WELDING ENGINEER INTERVIEWS QUESTIONS PART 1
Question 1. Why Should I Use A Robot For My Welding Needs?
Answer :
Switching from manual welding to a welding robot offers multiple advantages:
- Welding Robots are Cheaper - Robots are a one-time purchase. After factoring in all the money spent on the equipment cost and the hourly rate of a manual welder companies typically find that robots are a cheaper alternative for welding needs. To figure out the amount of money you can save annually by using a robotic system use our ROI calculator.
- Robots Offer Greater Accuracy - Robots, unlike humans, can be programmed to execute the same weld repeatedly without even slight alteration. They are capable of great precision. Robots are less likely to make mistakes. This in turn leads to a more reliable, high-quality product.
- Robots Conserve Resources - Robots won't waste your time or materials. Their programmed precision makes them less likely to waste products because of faulty welding. They work quickly without taking breaks, saving valuable hours and cost.
- Welding Robots Create a Safer Workplace - Welding can be hazardous to one's health. Robots are oblivious and protected against welding dangers like smoke, fire, fumes - taking humans out of potential danger.
Question 2. What Is Required When Shipping A Robot?
Answer :
- Unless specified otherwise, it is the customer's responsibility to arrange and pay for a confined air-ride box truck with an entrance no less than 110" tall and a width that can accommodate a forklift for loading and unloading the robot.
- Extra large systems that need flatbed trucking must be weatherproofed prior to shipping with a heavy-duty plastic tarp. Extra charges may apply with this option.

Question 7. Do You Only Integrate Robot Welding Applications?
Answer :
Welding-Robots.com represents the welding division of RobotWorx, an industrial robotics integrator capable of automating a wide variety of applications. While the welding division website provides customers with welding specific information, two other websites showcase our other services.
Question 8. What Is The Difference Between Mig And Tig Welding?
Answer :
- TIG and MIG arc welding can both be automated. However, TIG is a more complicated process so the equipment is more expensive and difficult to set-up. Find out more about the pros and cons of MIG vs. TIG.
- While Metal Inert Gas (MIG) and Tungsten Inert Gas (TIG) are both shielded arc welding applications, they are very different from one another. MIG welds are created with a consumable electrode, while TIG welds are created with a non-consumable electrode. TIG welding typically includes filler metal as well.
Question 9. What Is GMAW?
Answer :
Gas Metal Arc Welding is a welding method more commonly referred to as GMAW or MIG welding.
