I am trying aluminum tig for the first time and my rod does not connect to the work piece just turns into blob, i tried low and high amps, what am I doing wrong, I clearly dont know s**t about welding. 1/8" ER5356 rod and random 1/4" plate.

Mastering the interpretation of each division is a fundamental skill in welding, metal structures, carpentry and mechanization. Each mark represents a specific measurement, and understanding the difference between millimeters, centimeters and fractions of an inch allows you to make more precise lines, improve the adjustment between parts and reduce rework during assembly.

In the metric system, each centimeter is divided into 10 millimeters, whereas in the imperial system an inch is divided into fractions such as 1/2, 1/4, 1/8 and 1/16, frequently used in plans, tools and equipment of international origin.

Precise measurement is the basis of quality work. Before cutting, drilling or welding, always check the metric belt scale and confirm the reading to guarantee reliable results.

In SMAW welding, the electrode classification defines fundamental characteristics such as:
pe*******on, type of slag, polarity, mechanical resistance, hydrogen content and behavior of the electric arc.

Each electrode is designed for specific applications and selecting the wrong one can generate discontinuities, lack of fusion, porosity or loss of mechanical properties.

E6013
Rutile electrode for carbon steel. Produces smooth arc, low pe*******on and easy slag removal. Recommended for thin blades, aesthetic cords and light maintenance applications.

E6011
Cellulosic electrode with deep pe*******on and excellent stability on contaminated surfaces. Suitable for field repairs, oxidized structures and welding in forced positions.

E6010
High pe*******on cellulosic electrode designed for DC+ current. Used in welding tubes, root joints and critical joints where maximum pe*******on and control of the melt bath is required.

E7018
Low hydrogen electrode with minimum resistance of 70 ksi. Generates deposits of high mechanical quality and low susceptibility to seizing. Widely used in structures, bridges and heavy fabrication.

ENi-CI
Nickel-based electrode for molten iron repair. Reduce thermal stresses and minimize risk of cracking during industrial recovery and maintenance processes.

E308L
Austenitic stainless electrode with low carbon content. Used in stainless steel type 304/304L for sanitary and food applications and for conducting corrosive fluids.

The quality of a welded joint does not depend solely on the skill of the welder; It also depends on selecting the correct consumable according to the base material, welding position, type of joint and mechanical requirements of the project.

How the hell do I remove this?

I’m trying to remove this suspension component, but this rusted, castle-style nut is absolutely refusing to cooperate. I’ve tried loosening it, but everything is so corroded that I’m worried about damaging the surrounding parts. Is there a trick to getting this off, or am I looking at cutting the nut/stud? Any tips for dealing with something this badly rusted would be greatly appreciated!

In the coated electrode arc welding process (SMAW), the length of the arc directly defines the electrical behavior of the system, affecting variables such as voltage, metal transfer and fusion bath protection.

Arc – voltage relationship:

The greatest arc length → greatest voltage → most unstable arc
Shortest arc length → smallest voltage → short circuit risk

Operating conditions:

Short arch (5 mm):

Excessive voltage increase
Arc blow
High oxidation due to loss of protection
Splash increment
Presence of porosity and lack of fusion

Metallurgical implications:
An inadequate arc alters the solidification of the deposited metal, generating discontinuities such as slag inclusions, pores and zones of low structural cohesion.

Recommended technical parameters:

Arc length ≈ electrode diameter
Tilt angle: 15°–20° (push or drag according to application)
Constant forward speed to control the bathroom
Current adjustment according to electrode diameter (according to technical sheet)

Precise control of the arc length is essential to maintain process stability, optimize heat transfer and ensure the mechanical and metallurgical integrity of the welded joint.
