Understanding MMC and LMC in ASME Y14.5: A Detailed Guide

Aygün Karaköse
in Theory
6 0 Expert
In geometric dimensioning and tolerancing (GD&T), MMC (Maximum Material Condition) and LMC (Least Material Condition) are fundamental concepts that help ensure proper part fit and function during manufacturing and assembly. These concepts link the physical size of a feature with its allowable geometric tolerance, enabling more flexible yet controlled manufacturing.

How to Calculate Element Percentage in Weld Bead Using Dilution Formula

Aygün Karaköse
in Theory
3 0 Expert
This tutorial explains how to calculate the percentage of a specific alloying element (e.g. C, Mn, Cr, Ni) in a weld bead based on contributions from base metal, filler metal, and other additives. This calculation is critical in welding metallurgy to predict the final chemical composition of the weld and ensure mechanical properties meet standards.

Abaqus Welding Masterclass – The Only Tutorial You’ll Ever Need

FEAMASTER
in FEM
0 0 Beginner
This is the most complete Abaqus welding tutorial available on YouTube — a full-length masterclass that takes you from beginner to advanced welding simulation techniques using Abaqus. We start with a simple moving heat source (no subroutines), then simulate weld buildup using element reactivation. Next, we apply an analytical field equation to model heat input without writing code. From there, we dive into advanced simulations using the Gaussian DFLUX subroutine and then the Goldak double ellipsoid model for arc welding. Finally, we show how to predict residual stress after welding using actual temperature results. Whether you’re just starting or refining your workflow, this is the only Abaqus welding tutorial you’ll need. 🎥 Chapters Included: • Moving Heat Source Simulation • Element reactivation for weld buildup • Analytical field heat input • Gaussian DFLUX welding (laser simulation) • Goldak DFLUX welding (arc welding) • Residual stress prediction in Abaqus

🔧 Arc Transfer Modes in MIG Welding: Short Arc, Spray Arc, and Globular Transfer

Aygün Karaköse
in Theory
0 0 Expert
MIG (Metal Inert Gas) welding has become one of the most widely used welding processes in modern industry due to its high efficiency, automation capability, and compatibility with various materials. However, the type of arc transfer used in MIG welding plays a critical role in welding performance and quality. In this article, we explore the three main arc transfer modes in MIG welding: Short Arc, Spray Arc, and Globular Transfer — each with its own advantages and limitations. 🎯
