解析器有必要跟随链接并收集所有信息

我需要解析器从一个页面收集所有链接，然后它跟随这些链接并从那里收集所有信息。但是当代码执行时，只显示列表的最后一个组件svarka。

这是代码：

import requests
from bs4 import BeautifulSoup
import csv
import os

URL = 'https://ptk-svarka.ru/catalog/apparaty-poluavtomaticheskoy-svarki-mig'
HEADERS = {'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.138 Safari/537.36', 'accept': '*/*'}
FILE = 'svarka.csv'



def get_html(url, params=None):
    r = requests.get(url, headers=HEADERS, params=params)
    return r

def get_Stranic(html):
    soup = BeautifulSoup(html, 'html.parser')
    items = soup.find_all('div', class_='b-grid__item js-product-item')
    stranica_svarka=[]
    for item in items:
        stranica_svarka.append(
            item.find('a', class_='b-products__text').get('href'),
            )
    return stranica_svarka

def get_html_vivod(stranic):
    for url in stranic:
        r = requests.get(url, headers=HEADERS)
        r = r.content
        soup = BeautifulSoup(r, 'html.parser')
        items = soup.find_all('article', class_='b-product__wrapper')
        svarka = []
        for item in items:
            svarka.append({
                'title': item.find('h1', class_='b-product__title').get_text(strip=True)
                })
    return svarka

def parse():
    URL = input('Введите URL: ')
    URL = URL.strip()
    html = get_html(URL)
    if html.status_code == 200:
        stranic = get_Stranic(html.text)
        svarka = get_html_vivod(stranic)
        print (svarka)
    else:
        print('Error')


parse()
