Basic Usage
The basic usage of the "Pipe Welding Condition Calculator" is very simple. Just follow these steps to calculate the optimal welding conditions:
- Select the welding method (TIG welding, covered arc welding, etc.)
- Select the material and thickness to be welded
- Select the welding position (flat, overhead, horizontal, vertical)
- Select the size of the electrode or welding rod to be used
- Click the "Calculate" button to check the results
The calculation results will show the recommended current range and polarity (AC/DC). You can also record the actual current value used and notes, which will be helpful as a reference when welding under the same conditions next time.
Step-by-Step Guide
STEP1: Selecting the Welding Method
First, select the welding method you will use. This tool supports the following four welding methods:
- TIG Welding (with Back Shield): TIG welding using back shield gas. Suitable for high-quality welding requirements.
- TIG Welding (without Back Shield): TIG welding without back shield gas. Used in locations where back shield cannot be applied.
- AC Covered Arc Welding: Covered arc welding using alternating current (AC). Mainly suitable for non-ferrous metals such as aluminum.
- DC Covered Arc Welding: Covered arc welding using direct current (DC). Suitable for steel materials.
When you select a welding method, related setting items will be displayed automatically. For example, if you select TIG welding, electrode size and TIG filler rod settings will be displayed, and if you select covered arc welding, welding rod type and size settings will be displayed.
STEP2: Setting Material and Thickness
Next, select the material and thickness of the pipe to be welded.
Material Selection: You can choose from the following three main materials:
- Stainless Steel: SUS304, SUS316, and other stainless steel materials
- Carbon Steel: General carbon steel materials
- Aluminum: Various aluminum alloys
Thickness Selection: When you select a material, thickness options suitable for that material will be displayed automatically. For example:
- Stainless Steel: Various thicknesses from 0.5mm to 22.0mm
- Carbon Steel: Thicknesses from 1.0mm to 22.0mm
- Aluminum: Thicknesses from 1.0mm to 16.0mm
To get accurate calculation results, it's important to select the value closest to the actual pipe thickness. If the exact thickness is not available in the options, select the closest value and adjust accordingly.
STEP3: Selecting the Welding Position
Select the position in which you will perform welding. The recommended current value changes depending on the position, so it's important to select accurately.
- Flat (F): The most basic welding position where the weld part is horizontal and welding work is performed from top to bottom. Generally the easiest to weld, and high current values can be used.
- Overhead (O): A position where the weld part is overhead and welding is performed from bottom to top. Since molten metal tends to fall due to gravity, the current value is usually reduced.
- Horizontal (H): A position where the weld line is horizontal and welding work is performed horizontally.
- Vertical (V): A position where the weld line is vertical and welding work is performed from bottom to top or top to bottom. Since molten metal flows easily, the current value needs to be adjusted.
The recommended current range is automatically adjusted based on the welding position, so please select accurately according to the actual working position. For example, overhead and vertical positions recommend about 10-15% lower current values compared to flat positions.
STEP4: Setting Electrode and Welding Rod
The setting items displayed will change depending on the welding method selected.
For TIG Welding:
- Electrode Size: Select the size of the tungsten electrode (1.6mm, 2.4mm, 3.2mm). Generally, 2.4mm is commonly used, but 1.6mm is suitable for thin materials and 3.2mm for thick materials.
- TIG Filler Rod Size: Select the size of the filler material (filler rod) to use. You can also select no filler rod. An appropriate filler rod size is automatically recommended based on thickness.
For Covered Arc Welding:
- Rod Type: Select the type of welding rod according to the material. For example, for carbon steel, you can choose from "Low Hydrogen," "Ilmenite," "Lime Titania," etc.
- Rod Size: Select the diameter of the welding rod to use (2.0mm to 5.0mm). Generally, thinner rods are suitable for thin materials and thicker rods for thicker materials.
These settings directly affect welding quality, so it's important to select appropriately based on material thickness and welding position. For beginners in particular, it's recommended to start with the recommended settings.
