10 Easy Tips & Tricks for Improving Your MIG Weld to Pro

Step 9: Vertical Up Welding

Vertical up welding requires specific techniques to achieve optimal results. Here are two tricks to ensure a good vertical up weld:

Create a Triangle Shape: To maintain control over the weld pool and achieve proper fusion on both pieces throughout the vertical up weld, it is recommended to make a triangle shape. This technique helps to control the heat and maintain a consistent weld pool.

Adjust Wire Speed and Voltage: When performing a vertical up weld, it is necessary to adjust your wire speed and voltage settings compared to a standard down and butt weld. For instance, if you are welding 6mm steel with 0.8mm wire, the recommended settings for a down hand butt weld may be 23V and 12m/min wire speed. However, for a vertical up weld with the same parameters, it is advised to decrease the voltage to around 19-20V and the wire speed to approximately 6-7m/min. A general guideline is to reduce the volts by 3 or 4 and the wire speed by 5 or 6.

By making these adjustments, you can better control the heat input, minimize the risk of burn-through, and ensure proper fusion during vertical up welding. It is important to experiment and fine-tune the settings based on the specific materials and welding conditions to achieve the desired results.

Step 10: Achieving a TIG Like Appearance in MIG Welding

While a proper MIG weld is achieved by pushing the torch in a straight line, the final appearance may not always be visually appealing. However, if your weld will be visible to others, you may want to enhance its appearance. Fortunately, with some simple techniques and ample practice, you can achieve a TIG-like stack of dimes look using MIG welding.

Here are a few techniques to help you achieve a more aesthetically pleasing MIG weld:

Make your MIG weld look like a TIG weld

Please note these diagrams are to demonstrate tip movements, not speed of weld. That will depend entirely on your situation and settings.

Manipulate the Torch Angle: Experiment with manipulating the angle of the torch during the weld. Tilt the torch slightly back and forth or side to side to create a weaving motion. This can help create a stacked bead appearance similar to TIG welding.

Control the Wire Feed: Achieving the desired stack of dimes look requires precise control over the wire feed. Maintain a consistent and steady wire feed rate to ensure uniform bead appearance. Practice controlling the speed of wire deposition to achieve a stacked pattern.

Adjust Voltage and Amperage: Fine-tune your voltage and amperage settings to optimize the appearance of the weld. Experiment with different settings to find the sweet spot for achieving the desired stack of dimes pattern.

Practice and Patience: Obtaining a TIG like appearance in MIG welding takes practice and patience. Continuously refine your technique, focusing on maintaining steady hand movements and consistent torch positioning.

Remember that achieving a TIG like appearance in MIG welding may take time and effort. Regular practice, proper technique, and fine-tuning of settings are essential to enhance the aesthetic quality of your MIG welds.
